What are the classification of Metals

What are the classification of Plastics

What are the classification of Engineering materials

It is a term that is a qualitative or quantitative measure of response of materials to externally imposed conditions like forces and temperature

Just as classes of materials, there is some ______ among the properties, so the divisions are not always clearly defined

Classification of material property

Properties are related to transmission of heat and heat capacity. It is also related to its conductivity of heat

Different thermal properties

Properties includes absorption, reflectionc transmission and scattering of light

Types of optical

4 paradigmatic parameters of optica properties

Properties that are able to conduct electrical current

Materials with good thermal conductivity include ___ and ____

Give examples of electrically conductive materials

Property of material which resists the flow of electric current through material It is give-and-take of conductivity

Property of material which allow flow of electric current through material

Property of material which indicates ability of material to withstand a high voltage

It is the effect if lin formed by joining of two metals is heated, a small voltage of millivolt is produced Thermocouples Use to generate electicity and measure temperature changes

It indicates change in resistance of material with change in temperature

Ability of materials to act as a magnet and attract materials like iron, steel, nickel, etc

It is an example of magnetic properties, Process for heating metals and other electrically-conductive materials that is precise, repeatable and a safe non-contact method

3 classification of magnetic materials

Substances when placed in an external magnetic field produce negative magnetization (repelled by magnets)

Substances acquire a small net magnetic moment in the direction of the applied field (slightly attracted by the magnetic field)

Strongly attracted by the magnetic field(retain the magnetism even when magnetic field is removed)

Property of magnetic material which indicates that how easily magnetic flux is build up in material Determined by ration of magnetic flux density to magnetizing force to producing this magnetic flux density

An important material properties that firstly becomes magnetized and then de magnetization process

Defined as magnetizing force which is essential to neutralize completely magnetism in an electromagnet after value of magnetizing force become zero

It is related to changes in chemical composition of materials because it interacts with other substances When they come in contact with other substances they can react or deteriorate on its own to form a new material

What chemical should apply to prevent deterioration

In the Galvanic series chart, what is the most noble?

In the Galvanic series chart, what is the less noble?

Those distinguishing qualities or characteristics that are used to describe a subtance in the absence of external forces

It is the ratio of the density of a substance to the density of a reference substance.

The volumetric mass density of a substance is its mass per unit volume

A description of the physical behavior of material would include such characteristics such as

The properties of materials that determines its behavior under applied forces or external forces Expressed as the function of stress-strain

These are the internally distributed forces which tend to resist deformation

The deformation of a material from stress

Classification of mechanical properties

Defined as to which all of the variables affecting a given property are controlled and the property in question is measured under fixed conditions

The property of material by virtue of which deformation caused by applied loads disappears upon removal of load Temporary deformation

The amount of elasticity of a material is determined by two types of material parameter

Measures the amount of force per unit are needed to achieve a given amount of deformation. (Pascals)

Is its ability to undergo some degree of permanent deformation without rupture or failure and retain its new shape when the load is remove

Ability of a material to be deformed plastically under tensile load, and can be drawn out into fine wires without fracture

2 common measure of ductility

Abilitybof a material to be deformed plasticall under compressive load

Ability of a material to absorb energy during plastic deformation up to fracture

It is the property of sudden fracture without any visible permanent deformation

Property of a metal which gives it the ability to resist being permanently deformed when a load is applies

It is the failure of material under repeated or reversal stresses

The slow and progressive plastic deformation of a material with time at constant stress

It is related to interactions between surfaces and specifically the removal and deformation of material on a surface as a result of mechanical action of the opposite surface

Classification of wear

Factors affecting wear

They are qualities which give information regarding the suitability of metals for various technological operations or processes

What are the technological properties

Capability of a material to undergo plastic deformation to a given shape without defects

The ration of the actual strength of a structure or material (ultimate stress) to the maximum stress it should bear in service (allowable stress)

Formula of factor of safety

Formula of factor of safety (brittle)

Formula of safety of factor (ductile)

Low value of FoS indicates a ____

Is defined as the maximum stress that a material can withstand before failure where a force is applied

It refers to the maximum stress that a material can withstand while the material begins to deform plastically

Is that stress below which is is known that failure will not take place. Under static conditions this would be the elastic limit; under repeated stress, this would be the endurance limit

It is the actual stress under which the material is expected to operate
